I really don't understand all the negative reviews and such a low score this anime has gotten. I kept wanting to watch more of it, ended up watching it all in a day. It messes with my heart which I enjoy watching anime that do that to me, which isn't too often, and it was a good story. It was really good until the final episode, where it leaves us hanging a bit, but that makes me think of the possibilities that could have happened and messes with my emotions once again. Really good anime overall and I really enjoyed it.
